Abstract
The present invention provides a simple and robust design implementing an easily accessible external terminal connection point for supplying drive current to an AC motor. An embodiment of the invention is directed to an insertion plug and a conductor formed within the insertion plug. Specifically, the conductor acts as a current bus through an insertion aperture defined in a motor housing. The interior end of the conductor acts as an interior connection terminal for an AC phase coil, whereas the exterior end of the conductor is configured to accept an external motor drive source power cable. Advantageously, the modularity of the insertion plug design and a modified insertion housing aperture stamping program provide significant flexibility with regard to placement of the connection terminal. This aspect of the invention allows the connection terminals, as well as a corresponding motor housing to be customized for pre-existing mechanical designs and assemblies.
